How do I maintain the pristine exterior of my Audi A4?

I recently purchased an Audi A4 and want to make sure the exterior stays in top condition. What steps should I take to maintain the shine and protection of the paint?

Regularly wash your car with a mild car shampoo and a soft sponge or cloth to avoid scratching the paint.

Invest in a good quality wax or sealant and apply it every 3-4 months to protect the paint from UV rays and environmental contaminants.

Use a clay bar at least twice a year to remove any embedded dirt or contaminants that can't be removed through regular washing.
